Title: Improvements in or connected with feeding mechanism for metal presses and other machines and apparatus
IPC: B21D43/09
Filed: 1922-06-19
Abstract: 203,809. Sitton, A. June 19, 1922. Rod and bar feeds.-A detachable feed mechanism comprises rollers 29, 30, Fig. 2, mounted on intergeared spindles 27, 28, which are actuated by ratchet mechanism in such a manner that the duration and timing of the feed intervals may be independently adjusted. Means are provided to adjust the centre-line of the feed both vertically and horizontally and a continuously applied band brake 47 of adjustable spring tension is fitted to prevent retrograde movement of the ratchet wheel. The roller spindles are carried by blocks mounted in a vertical stand 21 which is horizontally adjustable on the machine bed 20. One of the roller blocks 23 may be set by means of a bolt 24 and slot 25 to adjust the height of the feed, the coacting roller block being slidable under spring pressure 55 to accommodate irregularities in the work. The ratchet mechanism consists of a radial arm 35a, Fig. 3, which carries a series of pawls 36 and is rocked by a connecting rod driven from a crank pin 41, Fig. 9, which is both angularly and radially adjustable relatively to the driving shaft of the machine by means of a detachable cap 43a and a graduated screw 70. The connecting rod may be curved and the journal bearings may be carried by universal joints to compensate for differences in the alignment of the driving and driven members. The ratchet drive may be disengaged by giving a slight angular movement by means of the lever 74 to a concentric plate 73 mounted in the oscillating member 35a, thereby causing transversely projecting fingers carried by the plate to trip the spring- pressed pawls 36. The ratchet mechanism may be of the ball or roller free-wheel type, in which case the plate 73 may operate wedges etc. to jam the balls or rollers in their free drive positions. The wheel 46 is provided with a knurled periphery so that the feed mechanism may be turned by hand. A guide nozzle 81, Fig. 14 fitted with interchangeable bushes etc. 84 to suit the stock being fed, may be incorporated with the feed mechanism.

Title: Improvements in or relating to artificial filaments
Inventor: JONES GEOFFREY HUGH
IPC: D01D5/253
Filed: 1964-04-25
Abstract: 1,086,873. Artificial filaments. IMPERIAL CHEMICAL INDUSTRIES Ltd. April 13, 1965 [April 25, 1964], No. 17268/64. Heading B5B. [Also in Division D1] Textile filaments consisting of at least one artificial high molecular weight polymer have cross-sectional shapes in the form of a quadrilateral with rounded corners, the sides of the quadrilateral being substantially straight. Preferred cross-sectional shapes are rhomboid, especially square and diamond and trapezoid, especially kite-shaped, it being understood that such shapes have rounded corners. Such filaments may be crimped and may be made by melt, wet, or dry spinning, from polyamides, especially polyhexamethylene adipamide, which is exemplified, polyepsiloncaprolactams, polyesters, e.g. polyethylene terephthalate, polyesteramides, polyhydrocarbons, polyurethanes, polycarbonates and their copolymers. Polymers based on acrylonitrile, cellulose acetate and polyvinyl chloride may also be spun by wet or dry spinning methods. Additives and fillers may be incorporated prior to spinning. Such filaments may also comprise two or more different synthetic high molecular weight polymer components existing in a contiguous relationship along the length of the filament, in either side-by-side or sheath-and-core arrangement. Such polymer components may have different shrinkage characteristics causing the filaments to crimp when heat relaxed in a substantially uncrimped condition. The filaments are made by spinning a polymer melt or solution through an orifice having a body portion and four limbs extending therefrom. For filaments of square cross-section a regular cruciform orifice with four equal limbs is used. For a kite-shaped cross-section a cruciform orifice having one limb longer than the other three is used and for a diamond the limbs may be arranged in the form of a diagonal cross with opposite limbs having equal dimensions and one pair being shorter than the other pair. In the examples, polyhexamethylene adipamide is melt-spun through a spinneret plate having regular cruciform-shaped orifices and the asspun are filaments wound-up and drawn at ratios of 3À7-4À66 to give filaments of the crosssection shown in Fig. 1.
